BUTTON.

SPECIFICATION forming part of Letters Patent No. 261,055, dated July 11, 1882. Application filed January 16. 1882. (No model.)

To all whom it may concern Be it known that I, HARRY A. SLAUGHTER, of Higginsville, in the county of Lafayette and State of Missouri, have invented certain new and useful Improvements in Buttons; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanyin g drawin g, which forms a part of this specification.

My invention contemplates a certain improvement in that class of separable buttons in which the head or top piece is provided with a tubular interiorly-threaded shank and the shoe or bottom plate with a central threaded stem, which may be screwed into the shank of the head, this connecting detachably the head and shoe.

The novelty consists in serrating the contiguous fiat faces of the head and shoe with concentric grooves, so that the circular ridges thus formed on one will fit into the corresponding concentric circular grooves of the other, substantially as hereinafter more fully de' scribed and claimed.

In the accompanying drawing I have shown a central sectional view of my improved button.

The letter B designates the head or top pieces, which is made in one piece with the tobular threaded shank A and disk 0, the flat under side of which has a series of concentric ribs or serrations, S, encircling the central stem, A.

D is the shoe or bottom plate, the upper face of which, around the central threaded stem, E, has a similar series of concentric serrations, S, so arranged that the circular and concentric ribs or ridges of disk I) will, when the parts are screwed together, enter or engage the circular concentric grooves or depressions of disk 0, thus firmly biting the fabric placed between my own I have hereunto aflixed my signature in presence of two witnesses.
